Visual studio 2012 slow unit testing

Question

Running unit tests on VS2012 is lately very slow, when I run them it takes about 12 seconds before they start actually testing.

When I debug it is the same story bef

Answer 1

This may not be related, but I noticed in some testing I was doing today that my Unit tests seemed to be running slower and slower. By chance I exited/restared Visual Studio and my tests are much faster now. There may be some sort of memory leak or other resource problem in the Unit Test mechanism. I am running update 1.
